Leeches were extensively used at one time. They had to be kept in something at home and these little glass pots are convenient with a flat rim to allow a covering to be tied on to prevent the leeches escaping. Comparison of the sizes of glass leech pots, from left to right below, large blue probably for a chemist shop, an 18th century clear handblown pot (10 cm tall), last two small for the home (all the small pots on this page are the same size, 5.5 to 6.5 cm, unless otherwise noted). Scratches on the inside of the bowl from use, fishing the leeches out, can be seen on some of the pots.

Until I recently bought the pot bottom right which is mould-blown, all the leech pots I owned were free-blown. Uranium pots in normal light:
Group of uranium pots in size comparison with cobalt blue and clear pots:
That green pot above looks like a leech pot without the flat rim. I wonder if it started life as a leech pot and got converted to a little posy bowl.

Anything in your home you'd want to look at nice as possible, even your pot for leeches. These fern-engraved leech pots on pedestals vary in height from just under 8 cm tall to just over 8.5 cm.
These are two of them close-up.
The fern-engraved pedestal pot on the left is quite different from the one on the right (and the others of that type above). It's heavy and has a heavy base. The rim is not flat but slanted up to allow a cover to be tied on. The engraving is much higher quality. The heavy base has facets cut on it.

18th century leech pots, larger than the other "small" ones, are 10 and 9.5 cm tall
the bases have snapped off pontil marks and deep kickups
All the following small leech pots are about the same size, ranging from 5.5 to 6.5 cm tall. The two smaller on the left have folded rims and appear older than the others.

This clear leech pot is a bit larger. It's 8 cm tall and has polished pontil mark on the base (will add photo).
Cranberry was obviously a popular colour for leech pots. these range from 5.5 cm tall to 6.5 cm tall
These are all hand-blown with snapped off pontil marks, except the one on the far left whose pontil mark has been polished.
This amber leech pot has a delightfully handmade look - well they all do! but this one isn't even properly round. 5.5 cm tall

These small pots are the same size as the classic leech pots but have a "fancier" feel, eg ribbing and better colours. (Now that I am processing them on my pc I see the photos are much too dark.) Better ones will be added shortly. Are they posies rather than leech pots? What would such a small posy really be useful for? What flowers would really work in them? If they are posies, why the flat rim? If everyone knew these were leech pots, which I suggest at one time they did, could they be used for something else? I suggest not. I'm reminded of the Exploratorium science museum toilet drinking fountain. It challenges! No one wants to drink from a fountain shaped like a toilet. No one would want to put any foodstuffs or flowers in a leech pot.
I bought some clear pots recently which pose more questions. They have larger openings and are slightly shorter, are they leech pots as well? The larger openings would certainly make fishing a leech out easier. They still have flat rims to tie a cover on but have the fancier ribbing and they have well-polished pontils showing some quality. Even though the pic is a little dark it shows the front row of clear pots are shorter.

The Old Operating Theatre museum at St Thomas' Hospital has some leech jars/pots in its collection:
This leech pot is from Guy Gaboriau's book, Outils de la sante et medecine d'autrefois, a great book about medical antiques.

A ceramic vase I use for bulb forcing but don't think it was made for that purpose, marked Britannia Ware S Hancock & Sons Stoke-on-Trent. Shape No 52. It features Charles I on one side.
both are heavy glass although the blue one (324g) is much heavier than the orange one (240g), they appear to be exactly the same size, I tried photographing one on top of the other and neither showed round the edge either order I put them in
above and below the flowers on both ashtrays are extremely similar
